Benefits of technology

[0007]The invention overcomes the above-noted and other deficiencies of the prior art by providing a surgical device for forming adhesive fasteners in one or more portions of tissue. The surgical device comprises a shaft and a first jaw extending from a distal end of the shaft and a second jaw extending from the distal end of the shaft. The second jaw is movable from a first position spaced away from the first jaw to a second position adjacent to the first jaw to clamp tissue therebetween. A fluid polymer adh

Problems solved by technology

The primary challenges in accomplishing this are control of getting the adhesive into the correct location at the correct time as well as preventing it from adhering the stapler itself to the treatment site.
One challenge in the creation of an adhesive fastener is the positioning of the adhesive into tissue and the forming of a fastener from adhesive.

twelfth embodiment

an Adhesive Fastener Device

[0141]FIGS. 13a-13e show the steps of use of a twelfth embodiment of an alternate embodiment of a surgical form in place fastening device 575 for creating an adhesive fastener 595 about an anatomical vessel. FIGS. 14a to 14c are a series of cross section of the fastening device 575 and vessel as the adhesive fastener 595 is created.

[0142]In FIG. 13a, an end effector 580 of the fastening device 575 is shown next to a vessel 510 that is surrounded by a bandage 511. A pivotable jaw 583 is shown opened relative to a fixed jaw 582. Both the pivotable jaw 583 and fixed jaw 582 contain a pivotable receptacle 585 and a fixed receptacle 586 for the reception of the vessel 510 and bandage 511 therein. Seals 587 are located at either end of receptacle 586 for sealing with the vessel 560 and bandage 561. In FIG. 3b, the vessel 510 and bandage 511 are clamped within the jaws 582 and 583 and the polymerizable adhesive 100 is flooding the receptacles 586 and 587. For thi...

thirteenth embodiment

an Adhesive Fastener Device

[0146]FIG. 14d can show an additional embodiment of the surgical fastening device shown in FIGS. 13a-13b including an additional pivot joint 609 to enable pivoting of the end effector as shown. The surgical fastening device 625 has an end effector 630 with a split jaws 632 and 633 that can pivot about a pin 610. A detent 634 (not shown) can be provided to detent the end effector 630 at a series of angles

fourteenth embodiment

an Adhesive Fastener Device

[0147]FIGS. 15a-15d show a fourteenth embodiment of a surgical fastening device 675 having an end effector 680 for that uses vacuum to create an adhesive fastener 695 within an anatomical vessel 560. The end effector 680 is attached to shaft 681 and has a pivotable jaw 683 and a fixed jaw 682 and vacuum ports 685. Pivotable jaw 683 is shown closed on vessel 560 and a vacuum is being applied from vacuum ports 685 to expand the vessel 560 within a vacuum chamber 686. A longitudinally movable hollow adhesive needle 670 can be filled with adhesive 100 and can extend through fixed jaw 683 aimed at the vessel 560. As shown in FIG. 15d, distal movement of adhesive needle 670 pierces vessel 560 and enables polymerizable adhesive 100 to be pumped into a lumen 567 of vessel 560 with piston 687. The vessel 560 fills with adhesive 100 which polymerizes to create the fastener 695 within vessel 560 as shown in FIG. 15b. FIG. 15c is a cross section of the severed vessel ...

Abstract

A fastening device for clamping and fastening tissue together with fasteners formed from an adhesive is disclosed. An embodiment of the adhesive fastening device can clamp a first and a second portion of tissue together between a first and a second jaw, and can place a fluid polymer adhesive into tissue and form it into a polymerized surgical fastener within the tissue. The adhesive fastener can be formed as a polymerized shank or shaft extending through the tissue, and can have one or more heads formed on the shank. The shank can be formed solely from the polymerizable adhesive, or can be formed from another material such as nitinol, titanium, stainless steel, suture, or a plastic. Shanks of other material can be combined with the adhesive. Alternately, an adhesive fastener can be formed extending distally from a distal end of the surgical device. And, an adhesive fastener can be formed around a luminal tissue or within luminal tissue.

Description

FIELD OF THE INVENTION[0001]The present invention relates, in general, to surgical fastening devices and in particular, to surgical fastening devices that can create fasteners from an adhesive.BACKGROUND OF THE INVENTION[0002]Adhesives and sealants have been contemplated to supplement or replace staple based transaction devices for many years. The primary challenges in accomplishing this are control of getting the adhesive into the correct location at the correct time as well as preventing it from adhering the stapler itself to the treatment site. Adhesives have proven themselves as great short term bonding / sealing mechanisms. In Europe, some surgeons prefer absorbable fasteners over non-absorbable fasteners such as staples. It would be advantageous to form or create fasteners from adhesive at the surgical site and more advantageous if the adhesive that was used to create the surgical fastener was absorbable.[0003]One challenge in the creation of an adhesive fastener is the position...
